Initial start-up and functions

1 Speaker Output

Speaker output to connect a subwoofer.

Never connect the loudspeaker cables with the car

chassis ground. It damages your amplifier. Ensure

that the loudspeaker systems are correctly con-

nected (phase), i.e. plus to plus and minus to mi-

nus. Exchanging plus and minus causes a total loss

of bass reproduction. The plus pole is indicated on

most speakers.

The impedance of the subwoofer should not be lo-

wer than 2 Ohms otherwise the amplifier could be

damaged.

2 Power & Protect LED

The power and protect LED indicates the opera-

ting mode of the amplifier. The power LED lights up

green when the amplifier is ready for operation.

If the protect LED lights up red a malfunction has

occurred.

A malfunction may have different causes as the

MATCH MA 10FX is equipped with different protec-

tion circuits. These protections shut off the ampli-

fier in case of overheating, over- and undervoltage,

short-circuit on loudspeakers and false connection.

Please check for connecting failures such as short-

circuits, wrong connections, wrong adjustments and

overtemperature.

If the amplifier does not turn on it is defect and has

to be send to your local authorized dealer for repair

service. A detailed description of the malfunction

and the purchase receipt has to be attached.

3 Fuse

The input fuses are connected in parallel and provi-

de protection against an internal fault of the device,

i.e. the system must be additionally protected by a

further line fuse located in the vicinity of the batte-

ry (max. distance from battery: 30 cm / 12"). The

MATCH MA 10FX is equipped with 2 x 25 Ampere

fuses.

4 + 12V

Connect the +12 V power cable to the positive ter-

minal of the battery. Recommended cross section:

min. 16 mm² / AWG 6.

5 REM

The remote lead should be connected to the remote

output / automatic antenna (aerial positive) output

of the head unit (radio).

This is only activated if the head unit is switched

on. Thus the amplifier is switched on and off with

the head unit.

6 GND

The ground cable should be connected to a com-

mon ground reference point (this is located where

the negative terminal of the battery is grounded

to the metal body of the vehicle), or to a prepared

metal location on the vehicle chassis, i.e. an area

which has been cleaned of all paint residues. Re-

commended cross section: min. 16 mm² / AWG 6.

7 Line Input

The MATCH MA 10FX is equipped with two RCA/

Cinch inputs. They can be connected with the pre-

amplifier output/s or line outputs of the signal sour-

ce (head unit, processor etc.).

In case only one of the signal inputs is connected,

the output level must be adjusted with the input le-

vel control control or a Y-RCA adapter can be used.

8 High Level Input

The MATCH MA 10FX is equipped with two extra

high level speaker inputs. They can be directly con-

nected to the speaker outputs of the head unit / car

radio.

The high level input is equipped with our special

‚Diagnostics Error Protection' circuit which makes

sure that the car radio detects the amplifier as a

speaker. Thus no functions of the radio will be de-

activated and no entry in the error log of the car will

be created.

We recommend to operate the high level input only

with the enclosed connecting cable or with a

MATCH cabe harness (optional).

The amplifier switches on automatically if a stan-

dard head unit is connected . The remote input has

not to be used.
